Control Via Tm54F - Siemens SINAMICS S120 Function Manual

Function
SS1/SS1E (time-controlled)
Selection until SBC is initiated
SS1 (time-controlled)
Selection until braking is initiated
The specified response times involve internal SINAMICS response times. Program run times in the F-host and the
1)
transmission time via PROFIBUS or PROFINET are not taken into account. When calculating the response times be-
tween the F-CPU and the converter, you must take into account that faults in the communication can result in a safety
function only being selected after the PROFIsafe monitoring time (F_WD_Time) has expired. The PROFIsafe monitoring
time (F_WD_Time) must also be included in the calculation when an error occurs.
t_K is the time for internal communication within the SINAMICS module; t_K can be determined as follows:
2)
For isochronous communication
For non-isochronous communication
p2048 is applicable for communication via IF1, p8848 for communication via IF2.
